How to make java (jax-ws) Client work with the WS SoapHeader ?

Question

I have a VB.NET webservice that uses a SoapHeader. I also have .Net client that works perfectly with it. but I am trying to write a Java client to work with the webservice but it looks like java doensnt work with SoapHeader (the sebserive doesnt get it (NULL))

I am new to Java and I feel its a setting issue

any help will be appreciated.
